ENGINE-STARTER.

Application led February 3, 1910. Serial No. 54158.20.

To all whom et may concern:`

Be it known that I, ELwoon C. ALLIsoN, a citizen of the United States, residing at `New York, inl the county of New York,

State of New York, have invented certain new and useful Improvements in Engine- Starters; and I do herebydecla're the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to engine starters and is .particularly designed for use in connection with explosive engines of the gas and gasolene type. l

. Thev primary object of the invention is to provide -an enginev starting device that can be manipulated from the seat of the automobile, when used' on such., and which is constructed of few parts, simply arranged and effectual in their operation.

With other objects in view than have been' speciically stated herein and which will be readily apparent to those skilled in the art to which the invention appertains, the

starter also includes those novel details of construction, .combination and arrangement of parts, all of which willv be described in detail, reference being had to the accompanying drawings wherein like characters of referencey denote corresponding parts in. the several views and in which, y Figure 1 lisa plan view of the forward end of an automobile with certain portions thereof omitted to expose to view the engine .and the 'improved starter mounted on the shaft of theengine; Fig. 2, a rear view of the starter showing one of the chassis of the -automobile in section with the forked" arm securedthereto which holds the starter against movement with respect to the longitudinal axis of the engine shaft; Fig. 3, a`

vertical section on the line 3 3 of Fig. 2;

. and, Fig. 4, a section on the line of Fig.l 3. Y

Referring to the drawing, A andB indi- 'cate the chassis of an automobile, C- the en'gine, D the engine shaft and E the crank for instituting the starting of the engine C in the usual and well-known manner.

The improved starting device which con-v stitutes the subject matter of this application is shown as .comprising va drum 10 having a grooved periphery 11 upon and from which is adapted to be wound and unwound a lcable l2.A The drum 10 is extended `centrally. of its front face as at 13 and said extension` and drum are provided with a common .central bore to permit same to be loosely mounted upon the engine shaft D. The wall of that portion of the central bore of the starting device' which is disposed within the limits of the extension 13 is rovided with a plurality of tapering poc {ets 14, in each of which is placed a steel roller 15 constituting a well-known form of clutch.

Specification of Letters Patent. Patented Oct. 25, 1910.

The rollers 15 are retained against 'longi-V tudinal displacement from, the pockets 14 by means of a ring plate 16 which is secured against the outer end of the extension 13. The chassis A of the automobile has secured thereto the vertical arm 17 of an angle iron, while the horizontal arm of said angle iron is bifurcated at its outer end and disposed on each side of the drum 10, said bifurcated horizontal 'arm serving to hold the starting device against movement with respect to the' longitudinal axis of the engine shaft. A friction wheel 18 is mounted on the fork of the bifurcated horizontal arm which is disposed in advance of the front face of the drum 10 to obviate possible binding from a .tendency of the starting device to slide forward on the engine shaft. A spring 19 has its intermediate portion disposed around the periphery of the extension 13 and one end disposed thereto in a fixed manner while its other` endis secured to the fork of the bifurcated horizontal arm which is disposed behind the rear face of the drum 10. The end of the cable 12 is carried over any suitable system of pulleys to a point adjacent the provided with a gripping handle.

In operation 'it will be apparent that in order to start the engine through the instrumentality of the device just described it will only be necessary for the driver to .seat of thev driver of the automobilepand pull with suiiicient force on the Vcable 12 to rotate the drum 10'on the engine shaft D,

such rotation beingin the direction of the ilo its normal position and the engine shaft will be free to rotate, without further effect on the starting device. i

F rom the above description it will be seen that a very ecient means is afforded for imparting the initial rotation of an internal combustion engine for starting the same with the motor easily accessible to and easily operated by the person on the seat of thevehicle. Y

What is claimed is:

` l. The combination with a vehicle and an explosive engine carried thereby for propeiling same, of a drum on the crank shaft of said engine, means for imparting the rotation of said drum in one direction to the crank shaft, automatic means for rotating the drum in the opposite direction energized by the rotation of the drum in the tiretA ling same, o a drum on the crank shaft of said engine, means for imparting the rotation of the drum in Vone direction to the crank shaft, automatic means for rotating the drum in thc opposite direction energized by the rotation of the drum in the first named direction, a forked member secured to the vehicle and embracing the drum and a friction Wheel journaled on one of the arms of said member and in engagement with one end of the drum.

3. The combination with a Vehicle and an explosive engine carried thereby for propelling Same, of a drum on the crank shaft of the engine, means for imparting the rotation of the drum in one direction to the crank shaft, automatic means for rotating the drum in the opposite direction energized by the rotation of the drum in the, first named`direction, said means comprising a projecting hub formed on the drum, a forked member secured to the vehicle and having its arms disposed partially across the respective ends of the drum, and a spring encircling said hub and having one end fixed thereto and theother end secured to one of the arms of said forked member.

In testimony whereof, I aiiiX my signature, in presence of two Witnesses.
